在无线中继网络中,通过合作通信的方式,分布空时编码是获得完全分集的一个重要途径。本文提出了部分相关分布空时编码的模型和得到完全分集的编码设计准则,推导出了在最大似然检测条件下成对错误概率的Chernoff限,介绍差分编码和译码的方案。

Distributed space-time coding is a means of achieving diversity through cooperative communication in a wireless relay network. The model of partially-coherent distributed space-time codes and code design criteria to achieve full diversity are proposed. The Chernoff bound on the pairwise error probability for ML detection is derived. The differential encoding and decoding scheme is introduced.
